Mrs. Schuldt says a trapezoid is a polygon that has exactly
one set of parallel sides.
Mrs. Nestor says a trapezoid is a polygon that has at least
one set of parallel sides.


Mrs. Schuldt says a trapezoid is a polygon that has exactly
one set of parallel sides.
Mrs. Nestor says a trapezoid is a polygon that has at least
one set of parallel sides. She’s right because
Parallelograms have 2 sets of parallel sides.
Which teacher is correct, according to the hierarchy
below?


What names describe the shapes below?

Triangle, equilateral, isosceles
Quadrilateral,
Parallelogram, rectangle,
rhombus, square


Why is a square a rectangle, but a rectangle
not a square?
Explain…

Why is a square a rectangle, but a rectangle not a
square?

A square is a rectangle because it has two pairs of
congruent sides, two pairs of parallel sides, and four right
angles. A rectangle is not a square because it does not
have all 4 sides congruent.
